The jailbreak community is responsible for creating many extremely useful utilities for our iDevices. This however, is not one of them.

Speed for Maps more likely falls in the “Hey, that’s kind of cool” category. This new jailbreak tweak installs itself in your native Maps application, and it places a speedometer in the bottom right corner…

The meter is there to show your real-time speed in the Maps application as you travel, and it’s also customizable. You can have your speed displayed in miles per hour, feet per second, kilometers per hour, meters per second, or even knots. Just open your Settings app to change the unit.

As Jeff says, I’m sure some folks will find this utility handy. But I rarely use the native iOS Maps software, so it’s tough thinking of a reason to keep it around. If you want to check Speed for Maps out for yourself, it’s available in Cydia as a free download.
